For those who don't know where the Crack of Time (CoT) is located, here's a handy video that helped me bookmark the locations:

The Crack of Time will bring you directly to Thebes Desert.

 

P.S. I noticed that one location is missing in the video, loc. 32914, 33163 (in the Oasis, Windawood)

 

Happy hunting!

Thanks for this.

Since I had a hard time finding when it's open, here is a link to the time Crack is open.

Tikal / Thebes Changes:

• Adding Tikal maps, bosses and items to the game.
• Thebes and Tikal now send you to Aden when you Escape or Restart.
• Increased drop rate of Ring of Thebes Osiris and Ring of Thebes Anubis to bring it in line with new Thebes updates and to increase competition with the bosses. They were never this rare on Live, and this allows more competition and fighting for bosses.
• The Crack of Time has been updated to spawn to a random map (Tikal or Thebes) 4 times a day! 6PM, 12AM, 6AM, 12PM (EST/EDT).
• The crack will stay open for 3 hours if the boss is not killed.
• If the boss is killed, the crack will stay open for 24 hours (Which rotates the next time it opens to the next spawn time so the same players cant kill the boss at the same time every day… each time zone will have a chance at killing TheBes/Tikal boss for drops).
• The bosses are only accessible 2.5 hours after the Crack has opened (there is a public announcement).
• Once the 30 minute timer is up, everyone inside is teleported out and the crack closes.
